Professor of the Leningrad branch of the Institute of Oriental Studies of the Academy of Sciences of the USSR Anatoly Nesterovich Genko was a polyglot scholar, who studied and scientifically described Chechen, Ingush, Abkhazian, Abaza and other languages of the peoples of the Caucasus. He was an author of the first edition of the monograph prepared for Abaza language. The manuscript of the book “Abaza language. Grammatical essay on Tapanta dialect” was ready in May 1934, but for some reasons it was released only 21 years later, in 1955. The author was arrested in late 1930s and died in prison in 1942. Anatoly Nesterovich made two research trips to Abazin villages of Cherkess Autonomous Region in 1929 and 1933. He visited auls, collected materials, recorded them using specially designed Latin characters, processed, organized, commented and translated them into Russian. Most of them were folklore materials such as tales, proverbs, satirical poems, historical legends and some real cases. After his arrest and subsequent death all scientific materials and studies of the scientist were kept in the State Archive of Leningrad (now – St. Petersburg), and only a few years ago were discovered by a folklore scholar, President of the Academy of Sciences of the Republic of Abkhazia Zurab Dzhotovich Dzhapua.
